Outline of presentation
Relevant WTO rules

Price and market mechanisms to internalize environmental cost

Price & market mechanisms to internalize
environmental cost
![Page 4: Current Developments in Domestic Climate Mitigation Measures](https://reader033.vdocument.in/reader033/viewer/2022051623/56815a72550346895dc7d398/html5/thumbnails/4.jpg)
Two Key Instruments
Tax on the carbon content of fossil fuels, often combined with a tax on energy use
Emissions Trading Scheme
![Page 5: Current Developments in Domestic Climate Mitigation Measures](https://reader033.vdocument.in/reader033/viewer/2022051623/56815a72550346895dc7d398/html5/thumbnails/5.jpg)
Effectiveness: Carbon tax vs. ETS
ETSCarbon tax
Price is determined directly by the regulators through the tax rate
(exogenously)
Price is determined by the market (endogenously)
Quantity of emissions to be reduced is a result of measures adopted by
industry to reduce emissions (endogenously)
Quantity of emissions to be reduced is determined by regulators
(exogenously)
Environmental uncertainty?
Price uncertainty?

Environmental effectiveness
2 key intended environmental effects of a carbon tax and an ETS
Direct effect, i.e. reduction of GHG
emissions, by setting a price on emissions
Indirect effect, through “recycling” of fiscal or auctioning revenues to
fund e.g. investment in more climate-friendly technologies

Border carbon adjustments
![Page 8: Current Developments in Domestic Climate Mitigation Measures](https://reader033.vdocument.in/reader033/viewer/2022051623/56815a72550346895dc7d398/html5/thumbnails/8.jpg)
Rationale
Emissions reduction policies
are not applied universally
Competitiveness loss
Carbon leakage
This may give rise to
![Page 9: Current Developments in Domestic Climate Mitigation Measures](https://reader033.vdocument.in/reader033/viewer/2022051623/56815a72550346895dc7d398/html5/thumbnails/9.jpg)
Rationale
In particular for energy intensive industries
However, effects are still uncertain
Concern: enhanced competitiveness (economic) of non carbon constrained producers could lead to ‘carbon
leakage’ (environmental)
![Page 10: Current Developments in Domestic Climate Mitigation Measures](https://reader033.vdocument.in/reader033/viewer/2022051623/56815a72550346895dc7d398/html5/thumbnails/10.jpg)
Border adjustment measures
To offset asymmetries in competitiveness
To avoid carbon leakage
Rationale

Relevant WTO Rules
![Page 12: Current Developments in Domestic Climate Mitigation Measures](https://reader033.vdocument.in/reader033/viewer/2022051623/56815a72550346895dc7d398/html5/thumbnails/12.jpg)
Relevant WTO rules
Key legal challenges for a case-by-case analysis
Coverage?
Consistency?
Justifiability?
![Page 13: Current Developments in Domestic Climate Mitigation Measures](https://reader033.vdocument.in/reader033/viewer/2022051623/56815a72550346895dc7d398/html5/thumbnails/13.jpg)
Coverage?
Importance to define the instrument at hand to determine relevant WTO/GATT provisions
A border adjustment to a tax?
A border adjustment to another carbon cost, e.g. an ETS?
![Page 14: Current Developments in Domestic Climate Mitigation Measures](https://reader033.vdocument.in/reader033/viewer/2022051623/56815a72550346895dc7d398/html5/thumbnails/14.jpg)
Two Situations
BTA on imports (equivalent to a domestic tax)
BTA on exports (i.e. a refund of domestic tax before exportation)
Implementation of the destination principleto ensure trade neutrality
The GATT Working Group on Border Tax Adjustments (1970)
Coverage?
![Page 15: Current Developments in Domestic Climate Mitigation Measures](https://reader033.vdocument.in/reader033/viewer/2022051623/56815a72550346895dc7d398/html5/thumbnails/15.jpg)
GATT Article II.2(a) provides for the possibility of imposing at any time on the importation of any product:
A charge equivalent to an internal tax in respect of the like domestic product or in respect of an article from which the imported product has been manufactured or produced in
whole or in part.
GATT Article III.2 covers “internal taxes or other internal charges of any kind”
Coverage?
![Page 16: Current Developments in Domestic Climate Mitigation Measures](https://reader033.vdocument.in/reader033/viewer/2022051623/56815a72550346895dc7d398/html5/thumbnails/16.jpg)
Submit emissions credits acquired abroad to cover the emissions during the production
process of the imported good
Hold emission allowances, up to the amount of CO2 emitted during the production of
imported products and applied on a per unit basis to each good
Potential requirements on importers
A border adjustment to a regulation, e.g. an ETS?
Coverage?
![Page 17: Current Developments in Domestic Climate Mitigation Measures](https://reader033.vdocument.in/reader033/viewer/2022051623/56815a72550346895dc7d398/html5/thumbnails/17.jpg)
GATT Article III.2
Can the price paid by an industry to participate in an ETS be qualified as an “internal tax or other internal charge of any kind”, covered under Article III.2?
GATT Article III.4
Can an ETS be seen as a measure covered by Article III:4, i.e. as a law, regulation and requirement affecting the internal
sale, offering for sale, purchase, transportation, distribution or use?
Coverage?

Consistency?
With basic principles, e.g. non
discrimination Most Favoured Clause
National treatment
Prohibition to discriminate between “like” products

Prohibition to discriminate between “like” products
Except if...
Consistency?

Justifiability?
Under certain conditions, Members can adopt trade-related measures aimed at
protecting the environment
WTO rules, as confirmed by jurisprudence
the right of Members to take regulatory measures to achieve
legitimate policy objectivesEssential to maintain
a balance betweenthe rights of other WTO Members
under basic trade rules
![Page 21: Current Developments in Domestic Climate Mitigation Measures](https://reader033.vdocument.in/reader033/viewer/2022051623/56815a72550346895dc7d398/html5/thumbnails/21.jpg)
Several disputes on measures that sought to achieve a variety of policy objectives
Conservation of clean air from air pollution
Protection of human health from risks posed by asbestos
Conservation of sea turtles from incidental capture in commercial fishing
Protection of human health from risks posed by the accumulation of waste tyres
WTO jurisprudence has confirmed that WTO rules do not trump environment, as long as…
Justifiability?
![Page 22: Current Developments in Domestic Climate Mitigation Measures](https://reader033.vdocument.in/reader033/viewer/2022051623/56815a72550346895dc7d398/html5/thumbnails/22.jpg)
…as long as several carefully crafted conditions are respected…
Environmental measures must not be applied in a manner which constitutes
a means of arbitrary/unjustifiable discrimination or
a disguised restriction on international trade
Justifiability?
![Page 23: Current Developments in Domestic Climate Mitigation Measures](https://reader033.vdocument.in/reader033/viewer/2022051623/56815a72550346895dc7d398/html5/thumbnails/23.jpg)
Implementation is key!
Major practical challenges in implementation
in assessing product-specific emissions
fluctuations of the carbon price
existence of carbon leakage
…
Justifiability?
